In order to ensure it can continue to provide safe and reliable electric service in this area, Oncor Electric Delivery Company LLC (“Oncor”) is proposing a rebuild of an existing 345 kilovolt (kV) double-circuit transmission line, including the addition of a new 138 kV circuit (the “Project”), all within Oncor’s existing right-of-way area. The Project will extend from the proposed Exchange Switch, which will be located southeast of the intersection of Interstate Highway 35W and State Highway 170 in Tarrant County, northeast to the existing Roanoke Switch, located north of State Highway 170, east of the intersection of Henrietta Creek Road and Chaparral Lane in Denton County.   

The proposed project will be approximately 3.5 miles in length and is currently planned for completion in 2025.

Voltage and Structure Type – The rebuild will replace each existing double-circuit lattice tower structure with two monopole structures. One monopole structure will accommodate an existing 345 kV circuit and a new 138 kV circuit. The other monopole structure will accommodate the second existing 345 kV circuit and include a vacant position for a future 138 kV circuit.
